Shimano Ultegra Di2 STI ST-R8060 2-/11-/12-speed Shift/Brake Lever

The Ultegra Di2 ST-R8060 Shift/Brake Lever by Shimano – More aerodynamic design
The Shimano Ultegra Di2 ST-R8060 STI shift/brake lever allows you to electronically upshift and downshift (2-speed or 11-/12-speed) and operate an SLR-EV rim brake on a time trial bike from an aerodynamic position. Unlike the predecessor ST-6871, the gearbox has been omitted, which makes the design even more streamlined. The ST-R8060 Dual Control lever scores with intuitive, fast shifting, adjustable grip width, numerous customisation options via the E-Tube platform and a side button (only to be used with Synchro-Shift). It can be mounted in handlebar ends with a diameter of 19 to 22.5 mm.

Shimano Total Integration (STI) means the combination of braking and shifting functions in one lever, which increases safety when riding. By refining the technology, it became possible to make shifting so smooth at the front and rear that they can be triggered with just one finger. Shimano calls such levers Dual Control Levers (DCL).

Digital Integrated Intelligence (Di2)
Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.
